DMN62D1LFD-13 Equivalent & Substitute Parts

Part Overview

The DMN62D1LFD-13 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 60V drain-to-source voltage with 400mA continuous drain current at 25°C. This device is housed in a 3-UDFN surface mount package and is designed for general-purpose switching applications requiring low on-resistance and compact form factor. The part is Active in product status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges for this MOSFET category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMN62D1LFD-13 is determined by equivalence in the following critical parameters: drain-to-source voltage rating (Vdss), continuous drain current capability (Id), on-resistance (Rds On), gate threshold voltage (Vgs(th)), and operating temperature range. All substitute parts must maintain Active product status and ROHS3 compliance. Package compatibility is evaluated separately based on circuit board layout requirements and thermal management considerations.

The DMN62D1LFD-13 has been identified with two substitute options: the DMN62D1LFD-7 from Diodes Incorporated, which is a parametric equivalent within the same product family, and the 2N7002WT1G from onsemi, which is a manufacturer-recommended alternative with comparable electrical characteristics but different packaging.

Parameter Comparison

Engineering Selection Recommendations

DMN62D1LFD-7 (Diodes Incorporated): This part is a direct parametric equivalent to the DMN62D1LFD-13, sharing identical electrical specifications and the same 3-UDFN package. Both parts are manufactured by Diodes Incorporated, maintain Active product status, and carry ROHS3 compliance with unlimited moisture sensitivity. The DMN62D1LFD-7 is suitable for direct substitution in applications where the 3-UDFN package footprint is already established in the circuit design. Higher inventory availability (23,300 pcs) may support supply chain continuity.

2N7002WT1G (onsemi): This part is a manufacturer-recommended alternative with the same 60V Vdss rating and operating temperature range. However, it differs in several electrical parameters: continuous drain current is reduced to 310mA (versus 400mA), power dissipation is lower at 280mW (versus 500mW), and gate threshold voltage is higher at 2.5V (versus 1V). The package is SC-70 (SOT-323), which is physically smaller than the 3-UDFN but requires circuit board layout modification. This substitute is applicable only when the reduced current rating and higher threshold voltage are compatible with the application requirements and when the smaller package footprint provides design advantage. All three parts maintain Active status, ROHS3 compliance, and unlimited moisture sensitivity.

Frequently Asked Questions (FAQ)

Q: Can the DMN62D1LFD-7 be used as a direct replacement for the DMN62D1LFD-13?

A: Yes. The DMN62D1LFD-7 is a parametric equivalent with identical electrical specifications (60V Vdss, 400mA Id, 2Ohm Rds On, 1V Vgs(th)) and the same 3-UDFN package. Both parts are manufactured by Diodes Incorporated and carry identical compliance certifications. No circuit modifications are required.

Q: What are the limitations of using the 2N7002WT1G as a substitute?

A: The 2N7002WT1G has three key differences: (1) continuous drain current is 310mA instead of 400mA, (2) power dissipation is 280mW instead of 500mW, and (3) gate threshold voltage is 2.5V instead of 1V. Applications requiring the full 400mA current capability or lower gate drive voltage cannot use this part. Additionally, the SC-70 package is physically smaller and requires different circuit board layout.

Q: Are all three parts RoHS compliant?

A: Yes. The DMN62D1LFD-13, DMN62D1LFD-7, and 2N7002WT1G are all ROHS3 compliant with unlimited moisture sensitivity (MSL 1). All three parts are Active in product status.

Q: What is the difference between the 3-UDFN and SC-70 packages?

A: The 3-UDFN (X1-DFN1212-3) is a 1.2mm × 1.2mm surface mount package used by the DMN62D1LFD-13 and DMN62D1LFD-7. The SC-70 (SOT-323) is a smaller package used by the 2N7002WT1G. Package selection affects circuit board layout, thermal management, and component density. Substitution between these packages requires circuit board redesign.

Q: Which substitute part has better availability?

A: The 2N7002WT1G has the highest inventory at 319,924 pcs. The DMN62D1LFD-7 has 23,300 pcs available. The original DMN62D1LFD-13 has 10,994 pcs in stock.

Q: Can I use the 2N7002WT1G in a high-current application requiring 400mA?

A: No. The 2N7002WT1G is rated for 310mA continuous drain current, which is below the 400mA requirement. Using this part in a 400mA application would exceed its current rating and may cause device failure or reduced reliability.

Q: What is the significance of the gate threshold voltage difference between the DMN62D1LFD-13 and 2N7002WT1G?

A: The DMN62D1LFD-13 has a gate threshold voltage of 1V, while the 2N7002WT1G is 2.5V. This means the 2N7002WT1G requires higher gate drive voltage to turn on. In applications with limited gate drive capability, the higher threshold voltage may prevent proper device operation or require circuit modification.
